Purpose: This phase III randomized trial (NCT00954174) tested the null hypothesis that paclitaxel and carboplatin (PC) is inferior to paclitaxel and ifosfamide (PI) for treating uterine carcinosarcoma (UCS)., Patients and Methods: Adults with chemotherapy-naïve UCS or ovarian carcinosarcoma (OCS) were randomly assigned to PC or PI with 3-week cycles for 6-10 cycles. With 264 events in patients with UCS, the power for an overall survival (OS) hybrid noninferiority design was 80% for a null hazard ratio (HR) of 1.2 against a 13% greater death rate on PI with a type I error of 5% for a one-tailed test., Results: The study enrolled 536 patients with UCS and 101 patients with OCS, with 449 and 90 eligible, respectively. Primary analysis was on patients with UCS, distributed as follows: 40% stage I, 6% stage II, 31% stage III, 15% stage IV, and 8% recurrent. Among eligible patients with UCS, PC was assigned to 228 and PI to 221. PC was not inferior to PI. The median OS was 37 versus 29 months (HR = 0.87; 90% CI, 0.70 to 1.075; P < .01 for noninferiority, P > .1 for superiority). The median progression-free survival was 16 versus 12 months (HR = 0.73; P = < 0.01 for noninferiority, P < .01 for superiority). Toxicities were similar, except that more patients in the PC arm had hematologic toxicity and more patients in the PI arm had confusion and genitourinary hemorrhage. Among 90 eligible patients with OCS, those in the PC arm had longer OS (30 v 25 months) and progression-free survival (15 v 10 months) than those in the PI arm, but with limited precision, these differences were not statistically significant., Conclusion: PC was not inferior to the active regimen PI and should be standard treatment for UCS., Competing Interests: Matthew A.

Background: Sorafenib and dacarbazine have low single-agent response rates in metastatic sarcomas. As angiogenesis inhibitors can enhance the efficacy of chemotherapy, we investigated the combination of sorafenib and dacarbazine in select sarcoma subtypes., Materials and Methods: Patients with leiomyosarcoma (LMS), synovial sarcoma (SS), or malignant peripheral nerve sheath tumors (MPNST) with up to two previous lines of therapy and adequate hepatic, renal, and marrow function received 3-week cycles of sorafenib at 400 mg oral twice daily and dacarbazine 1,000 mg/m 2 intravenously (later reduced to 850 mg/m 2 ). Patients were evaluated for response every 6 weeks. The primary objective was to determine the disease control rate (DCR) of sorafenib plus dacarbazine in the selected sarcoma subtypes., Results: The study included 37 patients (19 female); median age was 55 years (range 26-87); and histologies included LMS (22), SS (11), and MPNST (4). The DCR was 46% (17/37). Median progression-free survival was 13.4 weeks. The RECIST response rate was 14% (5/37). The Choi response rate was 51% (19/37). Median overall survival was 13.2 months. Of the first 25 patients, 15 (60%) required dacarbazine dose reductions for hematologic toxicity, with one episode of grade 5 neutropenic fever. After reducing the starting dose of dacarbazine to 850 mg/m 2 , only 3 of the final 12 (25%) patients required dose reduction., Conclusion: This phase II study met its primary endpoint with an 18-week DCR of 46%. The clinical activity of dacarbazine plus sorafenib in patients with these diagnoses is modest., Implications for Practice: Metastatic soft tissue sarcomas are a heterogeneous group of relatively rare malignancies. Most patients are treated with cytotoxic chemotherapy or targeted therapy in the form of tyrosine kinase inhibitors. Response rates are relatively low, and there is a need for better therapies. This clinical trial demonstrates that combining a cytotoxic therapy (dacarbazine) with an antiangiogenic small molecule (sorafenib) is feasible and associated with favorable disease-control rates; however, it also increases the potential for significant toxicity., Competing Interests: Disclosures of potential conflicts of interest may be found at the end of this article., (© AlphaMed Press 2018.)

Opinion Statement: Uterine leiomyosarcoma (uLMS) is a rare disease; in the data from the SEER database, 3165 cases of uLMS were diagnosed between January 2000 and December 2012. While a majority of patients (60%) are diagnosed with early stage disease, recurrence rates are high. Five-year disease-specific survival is 76% for patients with FIGO stage I and 60% for patients with FIGO stage II disease. Adjuvant treatments, including radiation therapy, chemotherapy, and combined modality approaches, have been explored with the goal of demonstrating improved survival. However, heterogeneous patient populations, small sample sizes, and lack of no-treatment control arms have limited the interpretation and reliability of the results from these studies. A randomized trial of adjuvant pelvic radiation compared to no additional treatment showed that adjuvant radiation did not improve recurrence or survival outcomes for early-stage uterine LMS. To date, no prospective, randomized trial has been completed comparing adjuvant chemotherapy to observation. A recent well-designed retrospective study showed that women treated with adjuvant gemcitabine-docetaxel had no improvement in progression-free or overall survival compared to women who received no additional treatment. Thus, current data support our recommendation against adjuvant radiation or chemotherapy treatment for patients with non-morcellated, completely resected, and uterine-confined leiomyosarcoma. We recommend that these patients be observed with periodic surveillance imaging and physical examinations.

Objectives: YWHAE-rearranged high-grade endometrial stromal sarcoma (HG-ESS) is a rare, recently defined uterine sarcoma harboring t(10;17)(q22;p13) resulting in YWHAE-NUTM2A/B fusion. Chemotherapy sensitivity of metastatic YWHAE-rearranged HG-ESS is unknown. We reviewed the response to chemotherapy in women with YWHAE-rearranged HG-ESS to provide guidance for clinical management., Methods: We retrospectively identified patients diagnosed with YWHAE-rearranged HG-ESS who received treatment for metastatic disease at our institutions. Cytogenetics or fluorescence in situ hybridization were performed in all cases to confirm rearrangement and, in conjunction with histopathology, a diagnosis of YWHAE-rearranged HG-ESS. Patient demographics, tumor histology, surgical procedures, radiation therapy, chemotherapy and treatment responses were collected., Results: Seven patients were identified with YWHAE-rearranged HG-ESS and met criteria for inclusion in this study. The median age at diagnosis was 45 (range 42-47). All patients had undergone hysterectomy with bilateral salpingo-oophorectomy. FIGO stage at diagnosis was IVB in four patients and a single patient each at stage IIIB, II or I. Median follow-up for the cohort was 27months (range 6-123). Six patients received anthracycline-based chemotherapy, with two of six achieving a complete radiologic response. One patient received gemcitabine and docetaxel, resulting in a partial response. For three patients who died from metastatic disease, survival from initial diagnosis was 33, 100 and 123months., Conclusions: For metastatic YWHAE-rearranged HG-ESS, prolonged disease control following diagnosis was seen, with notable responses to anthracycline-based therapy. This emphasizes the need for appropriate molecular testing of uterine mesenchymal malignancies and suggests that chemotherapy is an effective treatment option for metastatic YWHAE-rearranged HG-ESS., (Copyright © 2017 Elsevier Inc.

Purpose: Fixed-dose rate gemcitabine plus docetaxel achieves objective response in 35% of patients with uterine leiomyosarcoma (uLMS). This study aimed to determine whether the addition of bevacizumab to gemcitabine-docetaxel increases progression-free survival (PFS) in uLMS., Patients and Methods: In this phase III, double-blind, placebo-controlled trial, patients with chemotherapy-naive, metastatic, unresectable uLMS were randomly assigned to gemcitabine-docetaxel plus bevacizumab or gemcitabine-docetaxel plus placebo. PFS, overall survival (OS), and objective response rates (ORRs) were compared to determine superiority. Target accrual was 130 patients to detect an increase in median PFS from 4 months (gemcitabine-docetaxel plus placebo) to 6.7 months (gemcitabine-docetaxel plus bevacizumab). Treatment effects on PFS and OS were described by hazard ratios (HRs), median times to event, and 95% CIs., Results: In all, 107 patients were accrued: gemcitabine-docetaxel plus placebo (n = 54) and gemcitabine-docetaxel plus bevacizumab (n = 53). Accrual was stopped early for futility. No statistically significant differences in grade 3 to 4 toxicities were observed. Median PFS was 6.2 months for gemcitabine-docetaxel plus placebo versus 4.2 months for gemcitabine-docetaxel plus bevacizumab (HR, 1.12; P = .58). Median OS was 26.9 months for gemcitabine-docetaxel plus placebo and 23.3 months for gemcitabine-docetaxel plus bevacizumab (HR, 1.07; P = .81). Objective responses were observed in 17 (31.5%) of 54 patients randomly assigned to gemcitabine-docetaxel plus placebo and 19 (35.8%) of 53 patients randomly assigned to gemcitabine-docetaxel plus bevacizumab. Mean duration of response was 8.6 months for gemcitabine-docetaxel plus placebo versus 8.8 months for gemcitabine-docetaxel plus bevacizumab., Conclusion: The addition of bevacizumab to gemcitabine-docetaxel for first-line treatment of metastatic uLMS failed to improve PFS, OS, or ORR. Gemcitabine-docetaxel remains a standard first-line treatment for uLMS., (© 2015 by American Society of Clinical Oncology.)

Objective: Long-term survival for patients with advanced endometrial carcinoma is poor, and limited options exist for the management of recurrent disease. Our goal was to investigate the activity of doxorubicin in the second-line setting in patients who progressed after paclitaxel/carboplatin adjuvant treatment., Methods: We conducted a retrospective analysis of patients with recurrent endometrial carcinoma who were treated at Memorial Sloan-Kettering Cancer Center from 1995 to 2009 and who received paclitaxel/carboplatin adjuvant chemotherapy followed by second-line doxorubicin therapy at time of recurrence. The median progression-free survival (PFS) and overall survival times following paclitaxel/carboplatin and following second-line doxorubicin therapy were estimated using the Kaplan-Meier method. Toxicity was assessed by the treating physician at each visit and graded using version 4.0 of Common Terminology Criteria for Adverse Events. Patient presentation, treatment, patterns of recurrence, and patient outcomes were summarized., Results: Seventeen patients were included in study analyses. The median PFS from completion of paclitaxel/carboplatin was 8.0 months (95% confidence interval [CI], 4.5-13.6 months). At the time of recurrence, all 17 patients were treated with doxorubicin as second-line therapy. No patient achieved objective response of stable disease. The median PFS of this cohort following doxorubicin treatment was 2.1 months (95% CI, 0.95-2.7) months. Median overall survival was 5.8 months (95% CI, 1.0-15.0 months). There is only 1 patient still alive; her median follow-up time is 49.4 months. Predominant doxorubicin-related grade 2 toxicities included nausea/vomiting (18.8%), fatigue (18.8%), and neutropenia (12.5%). No grade 3 or 4 toxicities occurred., Conclusions: Among patients with advanced endometrial carcinoma who had received adjuvant paclitaxel/carboplatin, treatment with doxorubicin at time of disease recurrence failed to achieve any objective responses and was associated with a very short (2 months) time to progression. Doxorubicin may be considered inactive as second-line therapy in this endometrial carcinoma population.

Background: Between 30% and 50% of women who have high-grade uterine leiomyosarcoma (uLMS) limited to the uterus at diagnosis remain progression-free at 2 years. Adjuvant pelvic radiation does not improve outcome. The objective of the current study was to determine the 2-year and 3-year progression-free survival (PFS) among a prospective cohort of women who received adjuvant gemcitabine plus docetaxel followed by doxorubicin., Methods: Women with uterus-limited, high-grade uLMS and adequate organ function were eligible. Within 12 weeks of complete resection and after confirmation that they had no evidence of disease on computed tomography (CT) images, the patients received 4 cycles of fixed-dose-rate gemcitabine plus docetaxel. Those who were confirmed disease-free on CT scans after cycle 4 received 4 cycles of doxorubicin. CT imaging for recurrence was performed every 3 months for 2 years, then every 6 months for 3 years., Results: In total, 47 women were enrolled (46 evaluable) in 3 years. Characteristics included a median age of 53 years; 1988 International Federation of Gynecology and Obstetrics stage I disease in 81% of patients, stage II disease in 15%, and serosa-only stage IIIA disease in 4%; American Joint Committee on Cancer stage II disease in 13% of patients and stage III disease in 87%; a median tumor size of 8 cm (range, 2.5-30 cm); and a median mitotic rate of 18 mitoses per 10 high-power fields (range, 5-83 mitoses per 10 high-power fields). At a median follow-up of 39.8 months, 21 of 46 patients developed recurrent disease (45.7%). The median time to recurrence was 27.4 months (range, 3-40 months). Seventy-eight percent of patients (95% confidence interval, 67%-91%) were progression-free at 2 years, and 57% (95% confidence interval, 44%-74%) were progression-free at 3 years. The median PFS was not reached and exceeded 36 months., Conclusions: Among women with high-grade, uterus-limited uLMS who received treatment with adjuvant gemcitabine plus docetaxel followed by doxorubicin, 78% remained progression-free at 2 years, and 57% remained progression-free at 3 years. A randomized trial of adjuvant chemotherapy versus observation to determine whether adjuvant chemotherapy can improve survival in women with uterus-limited uLMS is underway., (Copyright © 2013 American Cancer Society.)

Objectives: High grade undifferentiated uterine sarcomas (HGUS) are rare, aggressive malignancies. Data regarding management are limited. We aimed to describe disease stage, response to treatment, and survival outcomes among patients with HGUS at our institution., Methods: We identified all patients with HGUS who received treatment at our institution from 1/2000 to 3/2011. Demographics, surgical procedures, disease stage, treatment response, and survival outcomes were abstracted from the medical records., Results: Twenty-one patients were identified. FIGO 2008 stage distribution was: I-7 (33%), II-1 (5%), III-2 (10%), IV-11 (52%). Eighteen of 21 patients (86%) undergoing primary surgical resection achieved a complete gross resection; however, progression within the abdominal cavity was identified in 11 patients (61%) by the time they underwent postoperative imaging. Of 13 patients who received first-line chemotherapy for measurable disease, the overall response rate was 62%. Responses were observed in patients treated with gemcitabine/docetaxel (6 of 8) and doxorubicin-based regimens (2 of 5). Progression-free and overall survivals for the entire cohort were 7.3 months and 11.8 months, respectively. In 14 patients with measurable disease at the time of treatment, 1-year survival was 35.7% versus 80% in 5 patients without measurable disease at time of treatment (P=0.112). Nine patients received second- or additional chemotherapy for progressive disease, with response rate of 19%. Time to progression was short among responders., Conclusions: HGUS represents a distinct histologic subtype of uterine sarcoma with poor outcomes regardless of stage at diagnosis. A majority rapidly develops distant metastases despite surgical resection. Gemcitabine-docetaxel and doxorubicin-based treatment achieved objective, but short-lived, responses in patients with measurable disease., (Copyright © 2012 Elsevier Inc. All rights reserved.)

Purpose: To determine the maximally tolerated dose (MTD) and pharmacokinetics of carboplatin plus KOS-862 (Epothilone D) a novel cytotoxic macrolide capable of causing mitotic arrest, in patients with advanced solid malignancies., Experimental Design: Patients who have progressed on standard regimens were treated at four different levels of KOS-862(mg/m(2))/Carboplatin(AUC): 50/5,75/5, 75/6 and 100/6 in a "3 + 3" phase I study study design to determine MTD. Patients received KOS-862 on Days 1 and 8, and carboplatin on day 1, of 3-week cycles. Pharmacokinetics of KOS-862 and Carboplatin were studied., Results: Twenty-seven patients enrolled in the study. At the top dose level, 2 out of the 9 patients experienced Dose Limiting Toxicity. (grade 3 peripheral motor neuropathy in both patients) Twenty-seven patients had sufficient plasma data points for pharmacokinetic analysis Both the parent drug, KOS-862, and the major inactive metabolite Seco-D KOS-862 (KOS-1965) were quantified in plasma. Kinetics of KOS-862 were the same as seen in monotherapy studies using the same route and time of administration. Two patients had tumor response after study treatment. Ten of 20 evaluable patients had stable disease after 2 cycles of study treatment. The MTD in the present study was KOS-862 100 mg/m(2) + carboplatin AUC = 6., Conclusions: The pharmacokinetics of KOS-862 were similar in this combination study to those seen in previous monotherapy studies using the same route and time of administration. We have described the MTD of this schedule. The neurotoxicity seen with this regimen should be considered prior to its administration in unselected populations.

Objective: GOG study 172 demonstrated improved progression-free (PFS) and overall (OS) survival for patients with stage III optimally debulked ovarian and peritoneal carcinoma treated with IV/IP paclitaxel and IP cisplatin compared to standard IV therapy. The inpatient administration, toxicity profile, and limited completion rate have been blamed for the lack of acceptance and widespread use of this regimen. We sought to evaluate the PFS, OS, toxicity, and completion rate of a modified outpatient IP regimen., Methods: Using a prospectively maintained database, we evaluated the outcomes of patients who underwent primary optimal cytoreduction for stage III ovarian, tubal, or peritoneal carcinoma followed by IV/IP chemotherapy from 1/05-3/09. Our modified regimen was as follows: IV paclitaxel (135 mg/m(2)) over 3h on day 1, IP cisplatin (75 mg/m(2)) on day 2, and IP paclitaxel (60 mg/m(2)) on day 8, given every 21 days for 6 cycles., Results: We identified 102 patients who initiated the modified IV/IP regimen and completed chemotherapy. The median follow-up was 43 months. The median age at diagnosis was 57 years (range, 23-76). Primary disease site was: ovary, 77 (75%); fallopian tube, 13 (13%); peritoneum, 12 (12%). FIGO stage was: IIIA, 8 (8%); IIIB, 4 (4%); IIIC, 90 (88%). Residual disease after cytoreduction was: none, 58 (57%); ≤ 1 cm, 44 (43%). The most frequent grade 3/4 toxicities were: neutropenia, 12 (12%); gastrointestinal, 8 (8%); neurologic, 6 (6%). Eighty-two (80%) of 102 patients completed 4 or more cycles of IV/IP therapy; 56 (55%) completed all 6 cycles. The median PFS and OS were 29 and 67 months, respectively., Conclusions: By modifying the GOG 172 treatment regimen, convenience, toxicity, and tolerability appear improved, with survival outcomes similar to those of GOG 172. This modified IV/IP regimen warrants further study., (Copyright © 2012 Elsevier Inc. All rights reserved.)

Purpose: Intraperitoneal (IP) cisplatin and intravenous (IV) or IP paclitaxel constitute a standard therapy for optimally debulked ovarian cancer. Bevacizumab prolongs progression-free survival (PFS) when included in first-line IV chemotherapy. In this study, the safety and feasibility of adding bevacizumab to a first-line IP regimen were assessed., Patients and Methods: Treatment was as follows: paclitaxel 135 mg/m(2) IV over 3 hours day 1, cisplatin 75 mg/m(2) IP day 2, and paclitaxel 60 mg/m(2) IP day 8. Bevacizumab 15 mg/kg IV was given after paclitaxel on day 1 beginning in cycle 2. After six cycles of chemotherapy, bevacizumab was given every 3 weeks for 17 additional treatments. The primary end point was safety and tolerability determined by whether 60% of patients completed six cycles of IV/IP chemotherapy., Results: Of 41 treated patients, 30 (73%) received six cycles of IV/IP chemotherapy and 35 (85%) received at least four cycles. Three (27%) of those who discontinued chemotherapy did so because of complications related to bevacizumab (hypertension, n = 2; perforation, n = 1). Grades 3 to 4 toxicities included neutropenia (34%), vasovagal syncope (10%), hypertension (7%), nausea/vomiting (7%), hypomagnesemia (7%), and abdominal pain (7%). There were three grade 3 small bowel obstructions (7%) during cycles 3, 9, and 15. One patient died following rectosigmoid anastomotic dehiscence during cycle 4. Estimated median PFS is 28.6 months (95% CI, 19.1 to 38.9 months). Three patients (7%) had IP port malfunction., Conclusion: The addition of bevacizumab to this IP regimen is feasible; however, bevacizumab may increase the risk of bowel obstruction/perforation. The observed median PFS is similar to that seen with IP/IV chemotherapy alone.

Purpose of Review: The combination of fixed-dose-rate gemcitabine and docetaxel has become an established treatment option for advanced uterine leiomyosarcoma and has demonstrated efficacy in nonleiomyosarcoma histology soft-tissue sarcomas. The activity of this regimen in advanced uterine leiomyosarcoma, other soft-tissue sarcomas, and pediatric sarcomas is discussed., Recent Findings: Fixed-dose-rate gemcitabine and docetaxel achieved high objective response rates in three prospective phase II studies as first-line or second-line therapy for advanced uterine leiomyosarcoma. In a randomized trial, the combination of gemcitabine and docetaxel was superior to gemcitabine alone in terms of objective response, progression-free, and overall survival among patients with soft-tissue sarcoma, most of whom had received at least one prior cytotoxic regimen. In a prospective phase II trial, four of 10 pediatric patients with sarcomas achieved complete responses with this regimen. In a small, prospective phase II trial for women with completely resected stage I, II, III, or IV high-grade uterine leiomyosarcoma, adjuvant treatment with gemcitabine-docetaxel was associated with a 2-year progression-free survival rate that appears superior to that of historical controls., Summary: Fixed-dose-rate gemcitabine and docetaxel is a reasonable treatment option for patients with advanced soft-tissue sarcoma. The regimen is a good choice as first-line or second-line therapy for advanced uterine leiomyosarcoma. The role of adjuvant gemcitabine-docetaxel in completely resected, uterine-limited, high-grade leiomyosarcoma is under investigation.

Objective: Patients with completely resected stages I-IV high grade uterine leiomyosarcoma are at high risk for recurrence. No adjuvant treatment has been shown to improve survival, although prospective data are limited. We sought to determine whether adjuvant gemcitabine-docetaxel would yield a 2-year progression-free survival of at least 50% in this leiomyosarcoma population., Methods: Eligible patients were treated with gemcitabine 900 mg/m(2) over 90 min days 1 and 8 plus docetaxel 75 mg/m(2) day 8, every 3 weeks for 4 cycles. CT imaging was performed at baseline, after cycle 4, and every 3 months. Progression was defined as evidence of new disease on CT., Results: Twenty-five patients (median age 49; range, 37-73) enrolled; 23 were evaluable (1-never treated, 1-ineligible). With median follow-up of 49 months for all patients, 10 (45%) of the 23 evaluable patients remained progression free at 2 years, with a median progression-free survival of 13 months. The median overall survival is not yet reached. Among the 18 patients with stages I or II uterine leiomyosarcoma, 59% remain progression-free at 2 years, with a median progression-free survival of 39 months. Median overall survival for stages I and II patients is not yet reached with median follow-up duration of 49 months. Sites of first recurrence were: lung only - 3/23 (13%); pelvis only - 5/23 (22%); both - 5 (22%)., Conclusions: Post-resection gemcitabine-docetaxel for stages I-IV high-grade uterine leiomyosarcoma yields 2-year progression-free survival rates that appear superior to historical rates. Gemcitabine-docetaxel merits further study as part of an adjuvant strategy for patients with completely resected, early-stage uterine leiomyosarcoma.

Purpose: To determine the progression-free survival (PFS) and overall survival (OS) in a cohort of patients who received either platinum-based chemotherapy with or without radiation therapy (pelvic or WAI), or RT alone., Methods: Memorial Sloan-Kettering Cancer Center (MSKCC) electronic medical records from 8/1/1995 to 10/3/2007 were reviewed for patient age, diagnosis date, type of primary surgery, residual disease at the completion of primary surgery, FIGO stage, treatment details, dates of progression and death, and site(s) of first recurrence. PFS and OS by stage (I/II v III/IV) and by treatment type (chemotherapy with or without RT v RT alone) were determined using landmark analyses 8 weeks after surgery. Patients who received chemotherapy with or without RT (pelvic or abdominal) or RT alone (pelvic or abdominal) were included in the analysis. Both groups were allowed to have received intravaginal radiation therapy (IVRT)., Results: Forty-nine patients met study criteria. Thirty-eight/49 patients received chemotherapy: 23/38 (60.5%) received paclitaxel-carboplatin; 7/38 (18.4%) received ifosfamide-platinum; 8/38 (21.0%) received other chemotherapy. FIGO stage was: I=15 (31%); II=5 (10%); III=21 (43%); IV=8 (16%). Three-year PFS for the entire cohort was 24%. Three-year OS for the entire cohort was 60%. Three-year median PFS time for the entire cohort was 15 months (95% CI: 11-25 months). Three-year median OS time for the entire cohort was 67 months (95% CI: 23-89 months). Three-year PFS for stages I-II was 43% v 14% for stages III-IV (HR=1.98 [0.9-4.33]); P=0.082. Three-year OS for stages I-II was 68% v 55% for stages III-IV (HR=1.26 [0.47-3.41]); P=0.648. Three-year PFS for chemotherapy with or without RT was 35% v 9% for RT alone (HR=1.74 [0.79-3.85]); P=0.164. Three-year OS for chemotherapy with or without RT was 66% v 34% for RT alone (HR=2.02 [0.77-5.33]); P=0.146., Conclusions: Our study corroborates GOG 150 results, and shows that paclitaxel-carboplatin appears to be an efficacious adjuvant chemotherapy regimen for completely resected uterine carcinosarcoma. The role of adjuvant RT in addition to chemotherapy warrants further investigation.

Purpose: To determine the maximally tolerated dose (MTD) of biweekly pemetrexed with gemcitabine plus B(12) and folate supplementation in patients with advanced solid tumors and ovarian cancer., Experimental Design: Patients with no prior pemetrexed or gemcitabine therapy enrolled in cohorts of three, expanding to six if dose-limiting toxicity (DLT) was observed. Pemetrexed, escalated from to 700 mg/m(2), was given before gemcitabine 1,500 mg/m(2) every 14 days. DLTs were grade 4 neutropenia lasting >7 days or febrile neutropenia, grade 4 or 3 thrombocytopenia (with bleeding), grade > or =3 nonhematologic toxicity, or treatment delay of > or =1 week due to unresolved toxicity., Results: The ovarian cancer cohort enrolled 24 patients with unlimited prior cytotoxic chemotherapies. MTD was observed at pemetrexed 600 mg/m(2), with 2 of 9 patients experiencing DLT. Most common grade 3 to 4 toxicities per patient were neutropenia (83%), leukopenia (67%), lymphopenia (73%), and febrile neutropenia (12%). Median cycle per patient was 8 (range, 1-16). Six of 21 (28%) patients had confirmed partial responses. Study protocol was modified for the solid tumor cohort (n = 30) to enroll patients with two or more prior cytotoxic regimens. MTD was observed at pemetrexed 500 mg/m(2), with 1 of 9 patients experiencing DLT. Most common grade 3 to 4 toxicities per patient were neutropenia (63%), lymphopenia (43%), leukopenia (70%) and febrile neutropenia (6.6%). Median cycle per patient was 4 (range, 1-20). Three of 29 (10.3%) response-evaluable patients had confirmed partial responses: 2 squamous cell carcinomas of head and neck and 1 nasopharyngeal cancer., Conclusion: MTDs for the solid tumor and ovarian cancer cohorts were reached at pemetrexed 500 and 600 mg/m(2), respectively, given biweekly with gemcitabine 1,500 mg/m(2).

Objective: Determine the safety and efficacy of cetuximab plus paclitaxel and carboplatin as initial treatment of stage III/IV ovarian cancer., Methods: An initial intravenous [IV] dose of cetuximab (400 mg/m(2)) was administered over 120 min followed by weekly IV infusions of cetuximab (250 mg/m(2)) administered over 60 min. Paclitaxel (175 mg/m(2)) and carboplatin (area under the curve [AUC] of 6) were administered IV every 21 days for 6 cycles. The order of administration was cetuximab followed by paclitaxel and then carboplatin. Patients achieving a clinical complete response after 6 cycles were eligible to continue weekly cetuximab for 6 months or until toxicity or disease progression. Safety was evaluated using NCI Common Toxicity Criteria version 2.0. Progression-free survival (PFS) at 18 months was determined and compared with historical controls., Results: Forty-one patients were enrolled in this study; 40 received treatment and were evaluable for toxicity, and 38 were evaluable for PFS. Grade 3/4 treatment-related toxicities included febrile neutropenia (12.5%), rash (2.5%), hypersensitivity reaction (7.5%), and hypomagnesemia (12.5%). Common grade 1/2 toxicities attributed to cetuximab included acneiform rash (82.5%), hirsutism (7.5%) or abnormal hair growth (25%), and nail disorders (22.5%), which in 3 cases resulted in the patient's discontinuation from the study. Median PFS was 14.4 months, and PFS at 18 months was 38.8%., Conclusions: The combination of cetuximab with paclitaxel and carboplatin is adequately tolerated as primary therapy for ovarian cancer but did not demonstrate prolongation of PFS when compared to historical data.

Objective: Doxorubicin-based treatment is standard therapy for metastatic uterine leiomyosarcoma. There is no standard second-line therapy. We determined activity of fixed-dose rate gemcitabine plus docetaxel as second-line treatment for metastatic uterine leiomyosarcoma., Methods: Eligible women with unresectable uterine leiomyosarcoma progressing after prior cytotoxic therapy were treated with gemcitabine 900 mg/m(2) days one and eight over 90 min, plus docetaxel 100 mg/m(2) on day 8 of a 21-day cycle with granulocyte growth factor. Patients with prior pelvic radiation received lower doses. Response Evaluation Criteria in Solid Tumors (RECIST) response was assessed by computed tomography (CT)., Results: Forty-eight of 51 women were evaluable for response (one wrong histology, two never treated). Prior therapy was doxorubicin-based in 90%, and ifosfamide-based in 6%. The overall objective response rate is 27%, with complete response in 6.3% (3/48), and partial response in 20.8% (10/48). An additional 50% (24/48) had stable disease (median duration 5.4 months). The median number of cycles per patient was 5.5 (range 1-22); 73% of patients remained progression-free at 12 weeks and 52% at 24 weeks. The predominant toxicity was uncomplicated myelosuppression: thrombocytopenia grade 3 (29%), grade 4 (10.4%); neutropenia grade 3 (12.5%), grade 4 (8.3%) anemia grade 3 (20.8%), grade 4 (4.2%). While pulmonary toxicity was reported, no patient had drug-related pneumonitis/hypoxia-type toxicity. Median progression-free survival (PFS) was 5.6+ months (range 0.7-27+ months). The median duration of objective response was 9+ months (range 3.9-24.5+ months)., Conclusion: Fixed-dose rate gemcitabine plus docetaxel is active second-line therapy for uterine leiomyosarcoma.

Objectives: Fixed-dose rate gemcitabine plus docetaxel is active as second-line therapy for metastatic uterine leiomyosarcoma. We sought to determine the activity of this regimen as first-line treatment., Methods: Eligible women with advanced uterine leiomyosarcoma were treated with gemcitabine 900 mg/m(2) over 90 min, on days one and eight, plus docetaxel 100 mg/m(2) on day eight, with granulocyte growth factor support on day nine of a 21-day cycle. Patients with prior pelvic radiation received lower doses. Patients were treated until progression or unacceptable toxicity. Response was assessed every other cycle by RECIST., Results: Forty-two women enrolled, with 39 evaluable for response. Objective responses were observed in 15 of 42 patients (35.8% overall; complete response 4.8%, partial response 31%, 90% confidence interval 23.5 to 49.6%), with an additional 11 (26.2%) having stable disease. Nineteen of 38 (50%) received six or more cycles of study treatment. Myelosuppression was the major toxicity: neutropenia grade 3 in 5%, grade 4 in 12%; anemia grade 3 in 24%; thrombocytopenia grade 3 in 9.5%, grade 4 in 5%. One patient had a grade 3 allergic reaction, 17% had grade 3 fatigue. One possibly-related grade 4 pulmonary toxicity was observed. The median progression-free survival (PFS) was 4.4 months (range 0.4 to 37.2+ months). Among 15 women with objective response, median response duration was 6 months (range 2.1 to 33.4+ months). Median overall survival was 16+ months (range:.4-41.3 months)., Conclusion: Fixed-dose rate gemcitabine plus docetaxel achieves high objective response rates as first-line therapy in metastatic uterine leiomyosarcoma.

The purpose of this study is to establish the maximum tolerated dose and define the dose-limiting toxicity of the investigational epothilone BMS-247550 in combination with fixed dose-rate gemcitabine. Patients with advanced, recurrent solid tumors who had received or=7 days occurred in one of six patients. Two of three patients in cohort 2 (gemcitabine 900 mg/m2 plus BMS-247550 30 mg/m2) had dose-limiting toxicities of grade 4 neutropenia. An additional three patients were treated at dose level 1 with no additional dose-limiting toxicities observed. At an intermediate dose level (gemcitabine 750 mg/m2 plus BMS-247550 30 mg/m2), two of six patients experienced a dose-limiting toxicity (febrile neutropenia and grade 3 hypophosphatemia in 1, grade 3 hypophosphatemia and grade 3 hyponatremia in (1), and five of six patients experienced dose delays. In the final cohort (gemcitabine 750 mg/m2 plus BMS-247550 25 mg/m2), two of two patients experienced a dose-limiting toxicity. Treatment-related toxicities included neutropenia, thrombocytopenia, neutropenic fever, hypophosphatemia, and hyponatremia. Nine of 14 patients evaluable for response had stable disease. The maximum tolerated dose for this schedule is gemcitabine 900 mg/m2 over 90 min days 1 and 8 plus BMS-247550 20 mg/m2 on day 8. Attempts to increase the dose of BMS-247550 by decreasing the gemcitabine dose did not sufficiently ameliorate myelosuppression. Stable disease was observed in some patients with prior taxane exposure.

Purpose: Gemcitabine as a single agent and the combination of gemcitabine and docetaxel have activity in patients with metastatic soft tissue sarcoma. To determine if the addition of docetaxel to gemcitabine improved clinical outcome of patients with metastatic soft tissue sarcomas, we compared a fixed dose rate infusion of gemcitabine versus a lower dose of gemcitabine with docetaxel., Patients and Methods: In this open-label phase II clinical trial, the primary end point was tumor response, defined as complete or partial response or stable disease lasting at least 24 weeks. A Bayesian adaptive randomization procedure was used to produce an imbalance in the randomization in favor of the superior treatment, accounting for treatment-subgroup interactions., Results: One hundred nineteen of 122 randomly assigned patients had assessable outcomes. The adaptive randomization assigned 73 patients (60%) to gemcitabine-docetaxel and 49 patients (40%) to gemcitabine alone, indicating gemcitabine-docetaxel was superior. The objective Response Evaluation Criteria in Solid Tumors response rates were 16% (gemcitabine-docetaxel) and 8% (gemcitabine). Given the data, the posterior probabilities that gemcitabine-docetaxel was superior for progression-free and overall survival were 0.98 and 0.97, respectively. Median progression-free survival was 6.2 months for gemcitabine-docetaxel and 3.0 months for gemcitabine alone; median overall survival was 17.9 months for gemcitabine-docetaxel and 11.5 months for gemcitabine. The posterior probability that patients receiving gemcitabine-docetaxel had a shorter time to discontinuation for toxicity compared with gemcitabine alone was .999., Conclusion: Gemcitabine-docetaxel yielded superior progression-free and overall survival to gemcitabine alone, but with increased toxicity. Adaptive randomization is an effective method to reduce the number of patients receiving inferior therapy.

This phase I study sought to determine the toxicity profile, pharmacokinetics, and antitumor activity of giving carboplatin every 3 weeks and paclitaxel weekly in patients with relapsed ovarian cancer. Eligible patients with relapsed epithelial ovarian cancer and prior treatment with platinum- and paclitaxel-based therapy were treated with an escalating regimen of carboplatin (day 1) at an area under the curve (AUC) of 4-6 and 1-h infusions of paclitaxel (days 1, 8, and 15) at 50-80 mg/m(2) cycled at 3-week intervals. Pharmacokinetic studies were performed on the first day of cycles 1 and 2. All patients had a platinum-free interval of greater than 6 months from the most recent platinum treatment. A total of 77 cycles were administered to 16 patients, with a similar median number of cycles per patient at each dose level varying from 4.6 to 5.3. Febrile neutropenia and grade 4 thrombocytopenia were the dose-limiting toxicities at dose levels 3 and 4 after the third cycle, with no mucositis, nausea, vomiting, or peripheral neuropathy observed greater than grade 2. The maximum tolerated dose of carboplatin was an AUC of 5 and 80 mg/m(2) for paclitaxel. Pharmacokinetic analysis showed a marginal statistical difference with regard to reduced systemic paclitaxel concentration after cycle 2 compared with cycle 1 (P= 0.06). Of nine patients evaluable for a radiographic response, the response rate was 66.6% with a complete response of 33.3%. All five patients with nonmeasurable disease achieved a biochemical response. The combination of carboplatin given every 3 weeks at an AUC of 5 and 1-h weekly paclitaxel at 80 mg/m(2) is a feasible and reasonably well-tolerated regimen and may have significant antitumor activity in relapsed ovarian cancer patients.

Objectives: Recent data suggest that differences in CA125 levels within the normal range may predict progression-free survival (PFS), but limited information is available regarding the value of these differences in predicting overall survival (OS) in patients with epithelial ovarian cancer. The objective of this study was to determine whether CA125 is an independent predictor of OS in patients with surgically defined disease status at the end of primary therapy prior to intraperitoneal (IP) consolidation chemotherapy. A secondary objective was to assess the relationship of CA125 level to PFS., Methods: Using data from a retrospective cohort of 433 patients who received intraperitoneal (IP) therapy following primary treatment for ovarian cancer between 1984 and 1998, we identified 241 patients with a complete clinical response and CA125 data at the time of second-look surgery prior to IP chemotherapy. Patient demographics and updated follow-up status were abstracted from medical records. Kaplan-Meier survival curves were compared using the log-rank test, and Cox regression models were used for multivariate analysis., Results: The majority of patients had advanced stage III or IV disease (n=201, 83%) and high-grade histology (n=163, 68%). Taxane was used as part of primary platinum-based therapy in 56% (n=134) of patients, and subsequent IP chemotherapy was platinum-based in 85% (n=206). When considered as a continuous variable, CA125 was a predictor of OS (P=0.029). Using the median CA125 level in our study group as a cut-off, OS was increased in patients with CA125 < or =12 U/ml (median 5.8 years) compared with >12 (3.7 years) (P=0.0027). CA125 level was an independent predictor of OS (HR: 1.410; 95% CI, 1.044, 1.904, P=0.0248) in a multivariate model that included stage (P=0.0166), grade (P=0.0001), and findings at second-look surgery (P=0.0003). CA125 level was also a predictor of clinical PFS (radiographic or CA125 elevation criteria alone) in a subset of 161 patients as a continuous variable (P=0.0036), and when divided at the median (< or = or >12; median 2.8 years vs. 1.7 years; P=0.0017)., Conclusions: In our study population, CA125 level at the end of primary therapy was a predictor of OS and PFS when considered as a continuous variable, or when divided at the median (< or = or >12 U/ml). Further prospective study is required to optimize clinically significant cut-off values within the normal range of CA125 levels for both OS and PFS endpoints.

The aim of this study was to assess the efficacy and tolerability of paclitaxel and carboplatin (TC) in the treatment of patients with advanced or recurrent endometrial cancer. Patients eligible for this retrospective analysis had endometrial cancer with either advanced or recurrent measurable disease (untreated primary stage III/IV or stage III/IV patients with persistent, measurable disease [> or =2 cm] after surgery), Eastern Cooperative Oncology Group (ECOG) performance status > or =3, and received at least one cycle of TC. Response rates were determined using Response Evaluation Criteria in Solid Tumors criteria. Institutional Review Board approval was obtained prior to the initiation of this study. Eighty-five eligible patients, with a median age of 62 years (range 36-80) were identified. Fifty-seven (67%) of patients were treated at the time of recurrence. Prior radiation therapy had been used in the treatment of 36 (42%) patients, while 13 (15%) patients had received prior chemotherapy. Median follow-up time was 11.7 months (range 1.1-96.7 months), and the median number of cycles of therapy received was six (range 1-18). The overall response rate (ORR) was 43%, with a complete response rate of 5% and a partial response rate of 38%. Chemotherapy-naive patients had an ORR of 47%. Only seven (8%) patients had to discontinue therapy due to toxicity. Median progression-free survival was 5.3 months (95% CI, 4.6-7.4), with a median overall survival of 13.2 months (95% CI, 11.7-18.2). We conclude that TC is an active and tolerable regimen in the treatment of patients with advanced or recurrent endometrial cancer.

Background: To determine the pathologic complete response rate of advanced ovarian cancer to weekly paclitaxel plus gemcitabine and carboplatin with filgrastim, and assess the longitudinal impact of this regimen on quality-of-life and cognitive functioning., Methods: Fourteen patients with advanced ovarian, peritoneal, or fallopian tube cancer were treated in the phase I portion of the study. Initial doses were paclitaxel: 60 mg/m(2) days 1, 8, and 15; gemcitabine: 800 mg/m(2) days 1 and 8; and carboplatin: area under the curve (AUC) 5 day 1, every 21 days for 6 cycles with filgrastim. Twenty-seven patients were treated at the phase II dose. Pathologic response was assessed by second-look laparoscopy in patients with complete response. Patients completed longitudinal assessments of quality-of-life and cognitive functioning., Results: Maximally tolerated doses were paclitaxel: 80 mg/m(2) days 1 and 8; gemcitabine: 800 mg/m(2) days 1 and 8; and carboplatin: AUC 5 day 1, every 21 days. Forty-eight percent of patients (13/27) experienced at least 1 grade 3 nonhematologic toxicity. Fifty percent (95% confidence interval [CI], 31-69%) of assessable patients achieved pathologic complete response. Median progression-free survival was 27.3 months (95% CI, 17.7 months to not reached), and overall survival 43.6 months (95% CI, 42 months to not reached). Cognitive functioning did not decline during or after chemotherapy. More highly educated women reported a perceived decline in concentration and memory while on chemotherapy. Quality-of-life scores were maintained during therapy., Conclusions: Fifty percent of patients with advanced-stage ovarian cancer achieved pathologic complete response to weekly paclitaxel plus gemcitabine and carboplatin. Cognitive functioning did not decline by objective measures, although highly educated women reported subjective impairment.

Purpose: Few chemotherapy agents are active in leiomyosarcoma (LMS), particularly LMS that has progressed after doxorubicin treatment. We sought to determine the response to gemcitabine plus docetaxel among patients with LMS., Patients and Methods: Patients with unresectable LMS of uterine (n = 29) or other (n = 5) primary sites who did not respond to zero to two prior chemotherapy regimens were enrolled onto a phase II study of gemcitabine 900 mg/m(2) intravenously (i.v.) on days 1 and 8 plus docetaxel 100 mg/m(2) i.v. on day 8 with granulocyte colony-stimulating factor given subcutaneously on days 9 to 15, delivered every 21 days. Patients with prior pelvic radiation received 25% lower doses of both agents. Gemcitabine was delivered over 30 or 90 minutes in cycles 1 and 2 and by 90-minute infusion in all subsequent cycles. Pharmacokinetic studies assessed in vivo differences in gemcitabine concentrations with different rates of infusion., Results: Thirty-four patients (median age, 55 years; range, 32 to 74 years) have enrolled. Fourteen had received prior pelvic radiation. Sixteen of 34 patients had progressed after doxorubicin-based therapy; 18 had no prior chemotherapy. Among 34 patients, complete response was observed in three patients and partial response in 15, for an overall response rate of 53% (95% confidence interval, 35% to 70%). Seven patients had stable disease. Fifty percent of patients previously treated with doxorubicin responded. Hematologic toxicity was common (neutropenia: grade 3, 15%; grade 4, 6%; thrombocytopenia: grade 3, 26%; grade 4, 3%), but neutropenic fever (6%) and bleeding events (0%) were rare. The median time to progression was 5.6 months (range, 4 to 10 months)., Conclusion: Gemcitabine plus docetaxel is tolerable and highly active in treated and untreated patients with LMS.

Epithelial ovarian cancer is the most lethal of all gynecologic malignancies. Most women have advanced stage disease. Access to appropriate initial surgical management by a gynecologic oncologist is important because treatment and survival are affected by appropriate surgical staging and debulking of tumor. After debulking/staging surgery, chemotherapy with platinum-taxane-based regimens is appropriate for most patients. Patients with early stage, low-risk tumors may be cured with surgery alone. Interval cytoreductive surgery may be appropriate for patients who are initially suboptimally cytoreduced and are stable or responding to chemotherapy. The role of second-look surgery remains to be defined. Patients with recurrent or relapsed ovarian cancer are incurable. There are several chemotherapy agents that can achieve disease responses, which may be associated with palliation of tumor-related symptoms. Participation in clinical trials is encouraged for all patients. Novel approaches to managing minimal residual disease are being tested in hopes of decreasing the number of patients who relapse after achieving complete clinical remission.

Objective: Anemia requiring red blood cell (RBC) transfusion is common in ovarian cancer (OC) patients receiving post-debulking surgery chemotherapy. Erythropoietin use has been shown to decrease transfusion requirements in patients receiving chemotherapy. We sought to identify pretreatment risk factors that could identify patients at increased risk for requiring RBC transfusion during first-line treatment for ovarian cancer., Methods: One hundred seventy-five consecutive patients who received chemotherapy with either carboplatin-paclitaxel or cisplatin-paclitaxel following debulking surgery for epithelial OC from 1993 to 1996 were identified. No patient received erythropoietin. Patient characteristics recorded included: age, stage, prechemotherapy hemoglobin, nadir hemoglobin, number of cycles and doses of chemotherapy received. The outcome was requiring RBC transfusion. Independent predictors of requiring RBC transfusion were identified using multivariate analyses., Results: Median age of the cohort was 62 years (range, 28-86). Seventy-one and four-tenths percent had FIGO stage III/IV disease. Median prechemotherapy hemoglobin was 11 g/dL (range, 7.1-15.4); median nadir hemoglobin was 9.3 g/dL (range, 6.6-11.1). One hundred nineteen (66%) patients received cisplatin-paclitaxel, and 61 (34%) received carboplatin-paclitaxel. Of 175 patients, 31 (18%, 95% CI = 12-23%) required RBC transfusion. Independent risk factors for RBC transfusion were prechemotherapy hemoglobin <10 g/dL (P < 0.01, odds ratio = 3.78, 95% CI = 1.52-9.44) and carboplatin-paclitaxel versus cisplatin-paclitaxel treatment (P = 0.01, odds ratio = 3.14, 95% CI = 1.27-7.76). Of 175 patients, 40 (22.8%) had a prechemotherapy hemoglobin <10 g/dL. Fifty percent of patients with prechemotherapy hemoglobin <10 g/dL who received carboplatin-paclitaxel required RBC transfusion, compared with 7.7% of patients with hemoglobin >10 g/dL who received cisplatin-paclitaxel., Conclusion: Ovarian cancer patients frequently require RBC transfusion during postdebulking platinum-paclitaxel chemotherapy. Patients with prechemotherapy hemoglobin <10 g/dL and those receiving carboplatin-paclitaxel are at increased risk of requiring RBC transfusion. Early initiation of erythropoietin use in such patients may reduce transfusion needs., (Copyright 2001 Academic Press.)

Objective: The objective of this study was to determine the clinical outcomes of patients with fallopian tube carcinoma treated with paclitaxel-based combination chemotherapy following primary cytoreductive surgery., Methods: Twenty-four patients with the diagnosis of primary tubal adenocarcinoma treated between 1993 and 1998 were identified through the gynecology service database and the Memorial Sloan-Kettering Cancer Center tumor registry. Medical records were reviewed for information on age, stage, chemotherapy regimen, surgical intervention, relapse, and survival. All patients had their histologic material initially read or reviewed at Memorial Sloan-Kettering Cancer Center prior to treatment. The original slides were reviewed again by one of the authors (P.E.S.) to confirm the diagnosis of primary fallopian tube cancer., Results: The mean age of the patients was 63 years (range, 44-76). Distribution by stage was as follows: four patients (17%) were Stage I, three patients (12%) were Stage II, 16 patients (67%) were Stage III, one patient (4%) was Stage IV. Four patients had grade 2 tumors, 20 had grade 3. Sixteen patients (67%) had optimal cytoreduction at the time of initial surgery with residual disease less than 1 cm. Eight patients (33%) had suboptimal cytoreduction. Following initial surgery, all patients were treated with paclitaxel-based chemotherapy for a median of five cycles. Twenty-three patients received paclitaxel at the dose of 135-175 mg/m(2) in combination with carboplatin or cisplatin; the majority, 17 of 23 (74%), received carboplatin. One patient received paclitaxel alone. Median follow-up from time of initial surgery was 24 months (range, 1-73 months). Two patients are dead of disease. Overall survival for the entire group was 96% at 12 months by Kaplan-Meier analysis, and 90% at 3 years. The overall median progression-free survival was 27 months (range, 5-57 months) for the entire group. The median disease progression-free survival at 3 years was 67% (95% CI, 45-100) in the optimally debulked group as compared with 45% in the suboptimally debulked group (95% CI, 27-57). Twelve patients (50%) had evidence of recurrence or persistent disease. There were fewer recurrences in the optimally debulked group: 5 of the 16 patients (31%) versus 7 of the 8 patients (88%) with suboptimal cytoreduction., Conclusion: Optimally cytoreduced patients with primary fallopian tube carcinoma treated with a paclitaxel-based chemotherapy regimen have an excellent possibility of survival., (Copyright 2001 Academic Press.)

Purpose: Recombinant interferon alfa-2b (rIFNalpha2b) is a standard therapy for chronic myelogenous leukemia (CML). Severe neuropsychiatric toxicity has been described in patients receiving rIFNalpha2b, although the frequency of and the risk factors for developing this toxicity are not well described. The purpose of this study was to identify predictors for the development of severe neuropsychiatric toxicity in CML patients receiving rIFNalpha2b-based therapy., Patients and Methods: From a prospective cohort of 91 Philadelphia chromosome-positive, previously untreated, chronic-phase CML patients treated on Cancer and Leukemia Group B (CALGB) 9013, a phase II trial of rIFNalpha2b plus cytarabine, the following were recorded at baseline: age, sex, race, pretreatment history of neurologic or psychiatric diagnosis, spleen size, blood counts, and peripheral blast count. Best response to treatment, rIFNalpha2b cumulative dose, dose duration, and dose-intensity were recorded during follow-up. Severe neuropsychiatric toxicity was defined as grade 3 or 4 events, according to CALGB expanded common toxicity criteria. Univariate and multivariate logistic regression analyses were used to identify variables that were associated with the development of severe neuropsychiatric toxicity., Results: Severe neuropsychiatric toxicity developed in 22 patients (24.0%; 95% confidence interval [CI], 15.2% to 32.8%). Toxicity resolved after withdrawal of treatment in all patients. Five of six patients developed recurrence of symptoms with rechallenge. Twelve (63%) of 19 patients with a pretreatment neurologic or psychiatric diagnosis developed severe neuropsychiatric toxicity, as compared with 10 (14%) of 72 patients without a pretreatment neurologic or psychiatric diagnosis (P =.001), resulting in a relative risk of 4. 55 (95% CI, 2.33 to 8.88) for developing severe neuropsychiatric toxicity. No other variables were independently associated with the development of neuropsychiatric toxicity., Conclusion: CML patients with a pretreatment history of a neurologic or psychiatric diagnosis are at significantly increased risk of developing severe neuropsychiatric toxicity during therapy with rIFNalpha2b plus cytarabine. Monitoring for neuropsychiatric symptoms and avoiding rechallenge are recommended measures for such patients receiving rIFNalpha2b-based therapy.
